The renewed interest in LED tube lighting

LED's are not new, they are the small red or green lights on the front of your stereo that tells you that the power is on. some consoles have quite a few of them to show the state of preparation of the equipment. However, there is a new wave of interest in LED tube lighting by manufacturers. There is talk of LED's being the future of lighting. In fact, there always has been these rumours about LED's, but nothing ever appeared to come of it.

Many more uses will be found for LED lights over the coming years. You will notice incandescent bulbs and even fluorescent tube lights being phased out in favour of LED lights as the issues are overcome, because LED lights is still in its early years.

This renewed interest in LED lighting started in 2004 when vehicle manufacturers took another look at using LED lighting in car headlamps. In 2008, Lexus produced the first ever car, the Lexus 600, with LED headlamps. These cars were exported all over the world except for North America. However, the 600's headlamps were or are not true LED headlamps, the main beam is produced by filament bulbs.

There are ways around this using heat sinks and cooling fans, but these answers are not ideal, so technicians and scientists are still looking for ways to resolve this problem. Conversely, the front of the LED lights produces almost no heat at all, so if there is vapour in the headlamp unit and the ambient temperature is below freezing point, then ice crystals will form over the LED's distorting and dampening the rays of light.

Nevertheless, scientists are confident that these teething problems will be surmounted and that LED lighting will one day be the most economical form of lights to use. In fact, it is already very inexpensive to use and the LED lighting units themselves last a long time. It is just the problem of overheating.

Besides their use in car headlamps, LED lights units can be seen in flashlights and in other parts of cars. Manufacturers are using LED lights more and more often in brake lights, flashing indicator lights and hazard warning lights, because there is no problem at all with these fairly low powered LED lights.

LED lighting used to be either green or red, but now it comes in more colours. White and blue are common. The coloured lights that you see under some cars are another instance of LED panel lights. They serve the useful purpose of making the car of motorbike more highly visible. All right, that may not be why they were installed, but nevertheless they increase the vehicles' visibility.
